CENTRIFUGAL SEPARATOR.

SPECIFIGATIONforming part of Letters Patent No. 560,637, dated May 19, 1896.

Application filed September 12, 1895. Serial No. 562,331. (No model.)

To all wleerwe--mrvlzfvoncerm v Be it known that I, ORRIN B. PECK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,

5 have invented a new and useful Improvement in Centrifugal Separators, of which the following is a specification.

My inventionv relates more particularly to improvements in separators for ore; and it consists in the various details ofl construction hereinafter described and claimed.

In the drawings, Figure l is a side elevation, parts being in section, of my improved separator. Fig. 2 is anend elevation thereof, looking from the right. Fig. 3 is a partial lon; gitudinal section on the line 3 of Fig. 2. Fig. 4 is a sectional detail, somcwhat'enlarged, on .the line 4 of Fig. 1. Fig. 5 is an enlarged partial longitudinal section on the line 5 of Fig. 2. Fig. 6 is a side elevation of a modification of my improved machine. Fig. 7 is an end elevation thereof, looking from the right. Fig. 8 is an enlarged lpartial longitu-- dinal section on the line 8 of Fig. 7, and Fig.

v5 9 is an 'enlarged partial transverse section on 'the'l'ine 9 of Fig. G. All sections are taken in the direction indicated by the arrows.

Like letters refer to like parts throughoutl the several views of the drawings.

A'designates a disk or wheel mounted on one end of a shaft A', suitably journaled in standards and rotated at the desired speed bya pulleyA2, belted to anysource of power.` At the center of the disk A is bolted a sub- 'stantiallyf cylindrical receptacle B,Vdivided into two concentric annular sections B' B2. yInto the former extends a pipe C, through which is fed ore or other material, preferably mingled with a suitable amount of water, and into the latter a pipe C', supplying clear wa- .,...ter. Withinvthe sections are a number of radialwings or webs C2, which compel the rotation with the receptacle of the bodyof material and liquid contained therein. From `the section B lead pipes D,fo`rming passages for the material. These pipes are tapered at their outer ends and pierced with orifices D',

About through which said material passes. .the pipes are shells or casings D2, forming with the pipes channels or passages D. These f shells are supported on brackets bolted tothe disk A. The form of that portion which en- 4section B2.

circles the ends of the pipes D corresponds nearly to them in form, but is of somewhat less abrupt inclination at the tapered portion, thus gradually widening the channels. The ends of the pipes D arennade adjustable toward and from the shells D2 to permit a variation in the width of the channels by Yproviding the ends entering the wall ,of the receptacle B with threads and placing on the pipes angular portions E, which maybe engaged by awrench to effect their movement. `When the orifices D become worn by the passage ofniaterial, these pipes may be removed and new ones substituted. Loek-nuts E' secure the pipes in place. y

The channels D" terminate in chambers F, formed by casing/s f, into which also lead pipes or passages F', communicating with the Opposite the end of the channely DIl in the outer Wall of the chamber F are dis charge-orifices F2, which deliver heavier material through an annular opening in a section G' of an encircling hood or annular trough G. 2 From the lowerend of the shells D2 lead pipes or passages H, forming a continuation ofthe passages D", surrounding the materialpipe and terminating in diseharge-orices Il for lighter material in 'another transverse plane from that inwhich lie discharge-oriees F2 and delivering to section G2 of the hood G. On the outer walls of the sections opposite the discharge-orifices are pointed annular ribs II2, which serve to deflect .the discharge to each side thereof, preventing the caking or accumulating of material on the walls from which it would drop back from above upon the separator. A horiaontal double trough li beneath the hood G receives heavier and lighter substances and conducts them away separately to desired points.

A ring I, secured near the outside of thedisk A, assists in supporting the chamber F and pipe II. The joints between various passages and chambers are made practically water-.tight to prevent leakage.

In operation the disk A and parts' supported thereby are rotated at a speed sufficient to develop the desired degree of centrifugal force. The ore or other material to .be separatcd in a finely-divided `state and mingled with a suitable quantity of water is fed by the pipe C into the section B', ,from which it passes IOO .the chambers F, which directit into the channels D, where it .meets the material flowingv in the opposite direction. The area of the passages or channels is so proportioned and may be further adjusted by the movement of the pipesl D, and the quantities of material and liquid-fed so arranged that there will be a resultant current inward through the channel of suihcient strength to carry with. it-

lighter substances against the action of centrifugal force,which iiowing back into the pipes H will be discharged thereby into the section G2 of the hood and 'conducted away. The heavier and valuable substances will have sufficient impulse impartedto them by the centrifugal force to carry them' through the inilowing water filling the channel and chamber toward the orifices F2, by' which they are discharged with some water into section G of the hood and conveyed to a suitable rcceptacle.

The area of the variousportions of the channel in which separation occurs is so propor-` tioned that there shall be in all parts an approximately equal resultant velocity of flow of the ore and water entering through orifices D' and from the chamber F, so that its impulse may be great enough to carry back into the pipes H allA substances b elow a certain specific gravity 'and' permit those above it to be forced through the iiowing liquid into the discharge-orifices F2.

The modification illustrated in Figs. 6 to 9 is in the main similar in construction and operation to that already described, but instead n of separated pipes and casings the passages and chambers are continuous and are formed between disks or plates 7c K K K2. The disks K K form between them the material-feeding passage D, While the water-feeding passage F is between disk K2 and the supporting-disk A, and Il, whichreceive's the lichter substances, is between K and K2. The separating-channel D is between the inwardly-turned peripheries of disks K2 K and inclined surfaces on K K. Transverse wings M, placed at intervals about the annular passage D, compel the rotation ofthe material at the same speed as the disks in a manner similar to the Wings C2 in the receptacles B' B2. Separate pipes L lead through the liquid-feedin g passage,c`on veying the lighter substances. Short tubes I. lead from disk li through the material-feeding passage and disk K and permit the lighter substances passing into the channel to the right of the disk l( to enter the dischargepassage.

The outer edge of the disk kis threaded and engages a thread on the interior of the bentouter portion of disk A. This enables '1; to be moved slightly to the right or left, thus permitting the width of the separating-channel to be adjusted. l

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a centrifugal separator, the combination of a rotatable receptacle, passages through which material is forced, means for eecting separation of lighter and heavier substances by forcing a current of liquid against the How of material, a channel or pas sage in which separation occurs, one of the wallsof which is provided with a screw-thread engaging a thread upon its support to permit adjustment to vary the width of such separating-channel, substantially as described.

2. In a centrifugal separator, the combination of a rotatable receptacle, a passage leading therefrom having a tapering end through which material is fed, and a tapering shell or casing surrounding the same and forming therewith a channel or passage graduallyincreasing in width as it extends outward, substantially as described.

3. In a centrifugal separator, the combination of a rotatable receptacle, apassage leading therefrom having a tapering end through which material is fed, and a tapering shell or casing 'surrounding the same and having a different inclination, thus forming a separating-channel the varying width of which maintains the velocity 'of-flow approximately constant throughout, substantially as described..

4. In a centrifugal separator-the combination of a rotatable receptacle, a passage leading therefrom having a tapering end through which material is fed, a tapering shell or casing surrounding the same and forming a channel or passage, one side of the channel being movable endwise to vary its width, substantially as described. v

5. In a centrifugal separator, the combination of a rotatable receptacle, a separatingv channel or passage rotating therewith, and a pipe leading from the receptacle to the channel adjustable to vary the width of the latter, substantially as described.

G. In a centrifugal separator, the combination of a rotatable receptacle, a channel in IOO IIO

which separation is effected extending outward from said receptacle, discharge passages for hcavier substances at one end thereof, and passages for discharging lighter substances from the opposite end continuous with the separating-channel and extending outward in a different plane, the openings of both passages being in proximity to a double receptacle, substantially as described.
